API, OpenAPI and WebMCP documentation

Explanation

Meters convert into earth radii using fixed astronomy size constants anchored to meters. Formula: R_earth = m × 1.56961013772e-7. That keeps the snapshot, calculator, table, and mirror page aligned on one constant basis.

It is useful for comparing planetary, stellar, and orbital-scale size references without switching between inconsistent reference tables.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Meter = 1.57e-7 Earth Radii.
Consistency rule: calculator output and table values use the same constants and rounding policy.

Questions & answers

Frequently Asked Questions

What is 1 meter in earth radii?

1 Meter equals 1.57e-7 Earth Radii on this page.

Does this Meters to Earth Radii page convert through meters first?

Yes. Standard metric units act as the shared size basis, and the astronomy reference unit is then applied through its fixed meter constant.

When would I convert meters to earth radii?

This route is useful when expressing planetary or stellar size references in metric units, or restating metric sizes in familiar astronomy reference scales.

How do I reverse Meters to Earth Radii?

Use the mirror Earth Radii to Meters route; it reverses the same astronomy size constants without changing the underlying assumptions.
